Red tail shark beating up my new red tail shark. Help!

I have an aquarium with a 1 year old red tail shark named Sharkie. I decided to get a playmate for him and got another one name her Soupie. I didnt realize at that time Soupie was a bit beat up. When I took her home Sharkie decided to bully her and she is all grey now and didn't put up a fight when I tried to catch her... and her fins are even more messed up. I put her in a separate tank for now, but is there anything else I can do for her?? I hope she makes it through the night....

Sorry you are having problems with your fish. You received good advice above about them being a one to a tank type of fish.

To nurse her back to heath I would recommend separating her into a tank with pristine water (0ppm ammonia and 0ppm nitrites with lots of water changes). I would also treat with Garlic Guard (or garlic juice form those little jars of garlic they sell at the supermarket), some Vita-Chem and also some Kardon Fish Protector.

You can soak her food in both Garlic Guard (or Garlic juice) and the Vita-Chem. Also Garlic Guard and Vita-Chem can be added directly to the tank. I've never used Fish Protector, but I believe that get added directly to the tank.

I have 2 red tail sharks in a 29 gallon tank. I bought them both at the same time & they're the same size. They seem like they are wrestling & fighting with each other, but not trying to hurt one another. There are no visible signs of fighting and stress. I do believe I only need one because the one that seems more aggressive doesn't swim around as much as the other. I don't think they are eating much, because every time I give them sinking wafers my cichlids eat them.
